Need A/C advice
 

Hi,

I just bought a 91 964 cab. I am so excited its been 28 years since my last p-car a 912.

Anyway the car had sat in storage for about a year and the a/c doesn't work. The compressor won't run. I assume its low on gas. Now my question is do I have it serviced and charged....only to leak out in a while or do I change over to the new R134 and live with the pinhole hoses. The other thought is to replace the hoses. Has anybody replaced these hoses and what is the approx. cost. I know this has been hashed around before, but I am still unsure what to do.

Thanks

Tom,

Take it to a good A/C shop and let them look at it. Its not black magic, but make sure that they realize that you cannot run the A/C in a 911 car with the back decklid in the "up" position. It will blow something, usually the HP hose. Attach the hoses and then lower the lid and recharge the system.

R22Tech would know more than most of us on this but I believe that they can leak check it without freon in the system.

I have heard that its about $500 or so for the parts alone to switch out the hoses. A local shop may be able to do it less but doubt that it would cost much less, and they would add labor to it to boot. Griffiths (www.griffiths.com) advertises in Pano and is one good source but hoses are generic.

Tom,

JA is right. Take it to a shop that does a/c and let them check it out. They can evacuate the system and let you know if it is leaking. If it does leak the next step is to find it.

A lot of times, when the a/c unit is not used for a long period of time, the refrigerant leaks out around the shaft seal on the compressor, because of lack of lubricant.

However, if your compressor is not running at all, you may have an electrical problem. Even if the unit is low on refrigerant, it will still short cycle.

I recently changed the liquid lines on my P-car to copper. Lot less leaking to worry about. Will eventually change the suction lines when they start to leak.
